if ur still in ur developmental stages (most men end it in their early 20's) SD can have a really big negative impact on you.
I am NOT supporting you however if u decide to run this u should know a few things.
1) at ur age and with the hormone ur messing with ur going to need pre and post cycle blood work so u know ur baseline values, u need a full metabolic panel to see cholesterol liver values and then a hormone panel of t3 t4 FSH LH all the testosterones and Estradiol.. You must get the pre done cause if u get all ****ed up off of ur cycle ur going to need to know what ur orginal/natural values are.
2) you need to run liver protection, taurine for potenial back pumps, a supplement for blood pressure, and ur going to need to probably get ur hands on some viagra or cialis, in my experience SD really messes up ur libido while on cycle.
3) understand what a proper pct is nolvadex XT and nolvadex are two completely different things u need to look into SERMS, as well as AI's because some people report delayed or rebound gyno from SD (gyno means bitch tits), and u either need a high strength AI to get rid of the gyno or some other protocol which i will not really get into right now.
4)if this is ur first PH keep it at 3 weeks thats all u will really want to do.
5) dont drink, this is a highly liver toxic oral and needs to be treated with respect otherwise u could cause permanent damage to the liver.
Now u asked for other advice so im going to give u a little help i think that will assist u in bulking and bodybuilding in general.
-ur probably over trained as of right now so just take a week off immediately.
- get your diet in order, clean carbs, high protein (300-500grams a day), reasonable fat intake. Calories on a bulk should be easily close to 5,000 a day.
-go look up DC, GVT and Starting Strength programs, write out ur plans and then use all 3 respectively, muscle grows way better with new stimulus presented rahter than doing the same old routine over and over.
-The name of the game is diet and training, you can inject all the testosterone or take all the mdrol you want, if ur only eating enough calories to support 200lbs of muscle you will never grow, u need food to make muscle.
